The Titan (high-current) and Nova (medium-current) system is combined into a single high-quality conditioning unit called Sigmas. Two high-current outlets feature essential elements of Titan’s Direct-Coupled© technology whilst the remaining four incorporate Nova’s Adaptive Gating© system, which auto-senses the requirements of the load.

  • Removes both Common Mode and Differential Mode mains noise.

  • RFI reduction 70dB.

  • Six unique conditioning stages ensure optimal isolation between each outlet, eliminating Differential Mode cross contamination.

  • 32,000A of instantaneous protection.

  • Internal wiring; solid core silver platted OFC copper with FEP and virtual air dielectric technology.

  • Two high-current outlets incorporate part Direct-Coupled© circuit and deliver low impedance 3,680W.

  • Four outlets feature Adaptive Gating©, which auto-senses the connected electronics and provides the optimal level of conditioning required at a maximum 1,380W continuous.

  • Available with UK, EU and US sockets.



The Sigmas takes many of the technological breakthroughs resulting from the Titan/Nova development projects and places them in a more affordable, yet still highly effective package. It bridges the gap between the new Aquarius and the Nova, incorporating many of the desirable aspects of the high-end Nova and Titan designs into a single chassis.

Through extensive design and an inspired balance of internal components, Sigmas endeavours to challenge the astonishing performance levels of the Titan and Nova. Like the Aquarius, Sigmas offers two high-current outlets and a further four medium-current connections for source components. However, Sigmas delivers an amalgam of top-end IsoTek® technologies, borrowing the Direct Coupled Design© and high-current aspects of the Titan, as well as Adaptive Gating© from the Nova.

For the aspiring high-end audiophile, Sigmas is a perfect solution delivering performance and versatility that’s unrivalled at the price. However, for those who crave the ultimate performance, the Nova and Titan combination still reigns supreme.

Sigmas ships with one of IsoTek's high quality power cables.
